Cover a bigger zone from the same footprint. The U240:1 puts 240 W into 70 V, 100 V, 4 ohm, or 8 ohm systems from a half-rack, 1U box, with efficient Class D amplification and a quiet temperature-controlled fan. Gain, bass, and treble sit on the rear panel — set once and walk away — and a priority emergency input keeps announcements landing. Two rack side by side in a single U. Restaurants, retail, schools, houses of worship, museums, galleries, transport hubs.
